tionally in the delivering position. A further object of our inventionis to obviate lossof liquid due to leakage of the tap and to provide atap which-is readily operated.

According to our invention the tap consists of a tubular body adapted'tobe attached to the desired vessel adaptor orelsewheraand having its freeend engaged by a springloaded closure member adaptedto be moved againstthe influence of the spring ldad to open said free endand to also open adischarge outlet in a sleeve *slidably dispo'sedabout said tubular body.

Simple arrangements of leversare adapted to move the spring loadedclosure member against the'infiuence of the spring, the'said leversbeing so l'oc ate'dand pivoted that a small rocking movement willbesuflicient to open *the tap and permit "the free flow of liquid.

In'order that our inventionmay be readily understood and carried intoefiect, We append hereto a sheet of'drawings illustrating variousembodiments and in which,

' Fig. 1 is apart sectional elevation of a tap constructed according toour invention.

Fig. 2 is afront endview of'Fig; 1.

Fig. '3 is an elevation of a modification showing an alternativearrangement of operating lever.

Fig. 4 is a front end view of Fig. 8.

Fig. shows an arrangement in'which the closure spring is arrangedoutside the body ofthe tap, this arrangement being particu-- larlyuseful when used for corrosive liquids.

Fig. 6 is a sectional view taken on line 8-8 of Fig. 5.. i v l Referringto Figs. 1 and 2, the tap which maybe made of any suitable metal oralloy consists of a tubular body rammed at one "end 2 and provided withsuitable nuts and washers 3 and 4 for attachment to theappropriate'bung'hole adaptoror other part of the container 620. tobe'tapped. The outer end of the tube 1 is machined externally at 5 toprovide a nice cylindrical surface. Fixed to the outer end of thistubular body is a collet 6 between the inner edge 7 of which and theinner edge 8 of a further collet 9 slidable on the tube 1 is a strongcoiled compression spring 10.

The slidable collet 9 is fixed inside the inner end of a sleeve 11concentrically disposed about the said tube and closed at its end by acap 12 which carries on its inner face a washer 13 composed of amaterial which will resist the action of the liquid being dispensed andabutting against the machined and if desired bevelled outer edge 14 ofthe fixed collet 6 thereby under the influence of the said springsealing the end of the tube.

The slidable sleeve has near its outer end an aperture 15 in its lowerside this aperture normally being covered by the fixed collet 6. When itis desired to dispense liquid this aperture is uncovered by sliding thesleeve outwards against the influence of the said spring and this actionalso moves the cap of the sleeve away from the outer end of the tubewith the result that the liquid will flow through the outer end of thetube into the sleeve and out through said aperture.

The opening movement of the sleeve can be effected by a lever 16 in theform of two symmetrical arms 16a pivoted at one end to a common bracket17 and fulcrumed on a common axis 18 to the slidable collet, the otherends of the arms being bridged by a horizontal handle 19. To open thetap the operator places the palm of a hand against the cap at the frontend of the sleeve and engages the said handle with the fingers. Agripping action will now compress the spring and open the said aperture.The tap is closed by merely releasing the handle.

The bracket to which the lever is connected can be a ring secured by anut 20 or otherwise about the threaded part of the tube and having adepending L shaped lug 21 to receive the two arms constituting saidlever.

In another arrangement shown in Figs. 3 and 4:, each of said arms can beL shaped, as at 22, the corner of each arm being fulcrumed at :3 to theliding sleeve ll and he o t-er end of the shorter limb 24 of each armbeing pivoted to said L shaped lug of the said bracket. The free ends ofthe other limbs extend slightly beyond said cap 12 and are bridged by ahandle 19 which is also adapted to be engaged by the finger of a handfor opening the tap, the thumb of the hand being pressed against a thumbrest 26 extending horizontally beyond and attached to said A furthermodification is illustrated in Figs. 5 and 6 showing a constructionwhich is particularly useful for corrosive fluids and in thisarrangement the spring 10 is shown to be out of contact with the liquidand surrounding the outer circumference of the sleeve 11 beinginterposed between a collet 39, secured to the said sleeve and a colletwhich is a sliding fit on sleeve 11 and secured by two diametricallyopposite rods 41 attached to the bracket 17 The rods 41 pass throughlugs 42 on the collet 89, these lugs also serving as pivots for thelevers 16. It will be seen that by placing the palm of the hand upon thecap 12 and grasping the lever 16 between the fingers that the sleeve 11with its collet 39 may be moved to overcome the pressure of the spring10 and allow the opening of the outlet aperture.

What we claim is 1. In a tap'of the type described a washer faced sleevelike body slidable on and adapted to abut against the outlet end of atube adapted to be inserted at its other end into a liquid container ora source of liquid supply, the washer normally sealing such outlet endof the tube and being mounted in one end of said sleeve like body, acoiled compression spring arranged between abutments carried by the tubeand sleeve and normally pressing said washer upon the outlet end of thetube, and a hand lever pivotally c011- nected to the sleeve and to thetube for moving said washer from the outlet end of said tube, the saidoutlet end of the said tube delivering into said sleeve like body, andan escape port in the side of said sleeve like body normally closed bythe side of the outer end portion of said tube.

2.
